NCT ID NCT05885048
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This observational study tracks 7,000 men and women with cancer to see how treatments like chemotherapy, radiation, and immunotherapy affect fertility. In women, researchers measure a hormone called AMH to gauge ovarian reserve; in men, they analyze sperm quality. The goal is to better understand which treatments pose the greatest risk to future fertility.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors better predict and discuss fertility risks before cancer treatment.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly improve fertility. Results may take years to gather and analyze.
